nhs Prof. De Candolle makes the cuspidatum, of Muhl and mild, a variety 

 of this- Our plant seems to present the principal characters of both. 

 9 D acuminatum, DC Stem erect, simple, pubescent, leafy at 

 .summit; leaflets ovate, the terminal one broader and orbicular-ovate 

 Tabruitly and conspicuously acuminate, sprinkled with appressed

ACUMIXATE DeSMODIUM. 



/Joo/ perennial. S/cm 9 to 15 inches high, striate-sulcate, sprinkled with soft 

 hall's,— the leaves all crowded near the summit. Leaflets 2 to 4 or 5 inches long, 

 and 1 to 4 inches wide,— the lateral ones obliquely ovate, the terminal ones larger,

 long, slender, minutely pubescent, finally scabrous ; lower bract linear-lanceolate, 

 nerved, ciliate. Calyx minutely hirsute ; segments ovate, nearly equal. Corolla
